5 Claims. (Cl. 12s-260) This invention relates to dispensing devices,and more particularly to that type of dispensing devices wherein thematerial tobe dispensed is extruded as required from the container.

The objects of the invention are to obtain an improved dispensing deviceof the character indicated in which the material may be extruded withoutshortening or squeezing the container;

vto provide such a device capable of being inserted into a cavity of thehuman body and the material extruded at the inner end of the container;,to enable the device to be promptly used without difficulty ofpreparation; to avoid the necessity oi' removing a cork or stopper; toprovide a complete device capable of reuse with new containers; tosecure simplicity of construction and operation; and to obtain otheradvantages and results as may bebrought out in the followingdescription.

Referring to the accompanying drawing, in which like numerals ofreference indicate similar parts throughout the several views;

Figure 1 is a side elevation of a dispensing device in accordance withour invention, showing the same ready to operate to extrude thematerial;

Figure 2 is a plan or end view of the device;

Figure 3 is a longitudinal sectional view, as upon line 3 3 of Fig. 1,but with the material partly extruded;

Figure 4 is a similar longitudinal sectional view of the container alonebefore the material is extruded;

Figure 5 is an elevation of a modiiled construction, and

Figure 6 is a longitudinal sectional view thereof on line 6 6.

In the specific embodiment of the invention illustrated in said drawing,the reference numeral I0 indicates the container for material II. Thecontainer is preferably of an elongated tubular construction with oneend closed until used and the other end open except for an appliedclosure such as the cork I2 shown in Figures 1 to 4 or the plunger headshown in Figures 5 and 6. In the construction of Figures 1 to 4, thisopen end of the container is shown as screwthreaded, the screw-threadsI3 being shown as pressed or moulded as part of the container. The corkI2 is applied to the container so as to be positioned .substantiallybelow the screw threads so as to leave a neck portion of the containerwhich is not filled or otherwise obstructed.

kAs a feature ofthe present invention, we provide a container which,while initially closed at one end as received by the consumer, yet itmay be punctured or otherwise opened thereat. In the drawing, isillustrated a hole Il at the tip end of the container, which hole, inFigures 1 and 4 is closed by an applied closure I5 such as paraiiin.However, it is to be understood that by use of puncturable material,such as a thin cellulose material, a preformed hole is not required, butmay be formed by puncturing when the device is to be used.

In order to extrude the material within the container through the holeor puncture, we pref-- erably provide means for forcing cork I2`longitudinally of the container.y Carrying out this feature, we haveillustrated a cap I6 hollowed out and threaded to be applied upon thethreaded end of the container. 'I'hrough this cap is slidably carried aplunger stern II having a plungerhead at its inner end adapted toretract into the hollowed-out part ofthe cap'.4v The cap may accordinglybe applied without disturbing the cork, and then by pushing inwardlyupon the stem the cork will be slid, without any tilting, as far asdesired. Preferably the container is of the right size so that itscontents will comprise a single dose or application, and therefore thecork will be pressed to the punctured end of the container to extrudevall of the material at one time under these circumstances.

The outer end of the stem Il may convenently be provided with anenlargement forming a flnger piece or button I8. By shaping the exteriorof the cap circumferentially concave, the same may beheld between twongers of one hand and the plunger pressed in with the thumb of the samehand. After the material has been extruded, the instrument, includingthe container, is withdrawn from the body, the container removed'andthrown away, and the cap, with its plunger, applied to a new containerready for use again.

In order to make it convenient to puncture the hole I4, we have shownthe outer face of the Abutton I8 recessed, as at I8, with a size andshape may be of such nature so as to be forced out by I6 internalpressure created when pushing the plunger against the material.

In the construction of Figures and 6, a unitary device including theplunger is shown, it being anticipated that the whole device will bediscarded after use. The body portion of the device preferably providesan elongated container 2| the outer end of which provides a reduced neck22 which expands thereabove into a cap portion 23, shown as hollow andlarge enough to receive the users finger. A plunger 24 is provided witha plunger-head 25 within the container, initially near the neck thereof,and with a stem 26 extending through said neck into the expanded portionoi the device. A nger-piece or button 21 is provided on the outer end ofthe stem enabling the plunger to be conveniently pushed inwardly. Theend of the expanded portion containing the plunger is preferablydiagonally open so as to more readily accommodate the users finger whenpressing the plunger its full length.

The end of the container opposite from the neck is puncturable to permitextrusion of the material Il within the container. Preferably the bodyportion is of inexpensive sheet material such as paper or. cellulosematerial, in which event it is convenient to draw the end of thecontainer together after the material has been intro-4 duced, andsealing by twisting the material thereat, by parafiining the same ifdesired, and by divers other means.

Obviously other detail changes and modifications may be made in theconstruction and use of our improved dispensing device-without departingfrom the spirit or scope of the present invention, and we do not wish tobe understood as limiting ourselves to the precise details shown ordescribed except as set forth in the following claims when construed inthe light of the prior art.-

Having thus described the invention, We claim:-

1. A dispensing device comprising an elongated container having one endthereof open and the other end closed, said closed end being constructedso as to rupture for discharging the contents, said open end having acork within the same spaced inwardly from the open end for preventingwithdrawal of the cork and discharge of the contents from the open end,and said container providing means between the cork and open end forretaining the cork spaced inwardly within the container.

same spaced inwardly from the open end for preventing withdrawal of thecork and discharge of the contents from the open end, said containerhaving its wall next the open end spirally impressed with a screw threadthereby providing means between the cork and open end for retaining thecork spaced inwardly within the container.

3. A dispensing device comprising an elongated container having one endthereof open and the other end closed, said closed end being constructedso as to rupture for discharging the contents, said open end having acork within the same spaced inwardly from the open end for preventingwithdrawal of the cork and discharge of the contents from the open end,said container having its wall next the open end spirally impressed witha screw thread thereby providing means between the cork and open end forretaining the cork spaced inwardly within the container, and means forpushing the cork longitudinally inward of the container, said meanscomprising a cap threaded on to the exterior of said spirally threadedportion of the container and a plunger slidable in said cap and having aplunger head of less diameter than the cork and insertable through theimpressed screw threads of the container.

4. A dispensing device comprising in combination with a container havingone end screwthreaded and receiving a cork inset from said end, theopposite end of the container adapted to be opened in use, a cap adaptedto be applied to said screw-threads, and a plunger passing through saidcap and having an inner end adapted to engage and push the cork towardthe opened end of the container.

5. In combination, an elongated capsule-like container for substantiallycomplete and unprotected insertion in a body orifice, one end of saidcontainer being closed and the other end open, said closed end beingconstructed so as to rupture for discharging the contents in said bodyorifice, said open end having a cork for retaining the contents and alsohaving means for mounting the container by its said open end formaintaining the container unenclosed for substantially its entire lengthwhen mounted, and means applicable to the said mounting means forsupporting the said container in use, this last said supporting meansproviding operative mechanism for impelling the cork and contentslongitudinally of the container toward the closed end for impelling thecontents through the rupture thereof.
